ATTACHMENT C <br /> The Climax seed mixture has evolved over the last 23 years of <br /> testing and utilization. It has gained a well deserved repu- <br /> tation for success under the environmental extremes of high <br /> altitude and poor soils and is in widespread use in North <br /> America . The seed mix presently is being tested on high <br /> altitude mine sites in Chile. The Climax mix will continue <br /> to evolve and change as research results from the mine site <br /> and other high altitude areas develop over the years. Cur- <br /> rently, the Climax seed mix consists of the following species <br /> and percentages : <br /> Percentage <br /> Species by Weight <br /> Rye (Secale cereale ) 20% <br /> SmootF Brome Bromus inermis ) 15% 1 <br /> White Dutch Clover Tri o ium re ens ) 10% <br /> Creeping Foxtail (Alopecurus arundinaceus ) 9% <br /> Creeping Red Fescue ( festuca rubra ) 8% <br /> Hard Fescue ( Festuca oviina) 7% <br /> Timothy ( Phleum pratense ) 58 <br /> Orchard Grass ( Dactylis glomerata ) 5% <br /> Cicer Milkvetch (Astragalus cicer ) 4% <br /> Arizona Fescue ( Festuca arizonica ) 4% <br /> Kentucky Bluegrass ( Poa pratensis ) 3% <br /> Redtop (Agrostis alba-7 3% <br /> Big Bluegrass ( Poa ampla ) 3% <br /> Canada Bluegrass ( Poa com ressa ) 2% <br /> Canby Bluegrass ( Poa canbyi ) 2% <br /> The Climax mix is applied at a rate of 50 lbs_. _der acre on <br /> all slope and site types . The short growing season and cool <br /> temperatures on the property allow seeding to occur through- <br /> out the snow free period . <br /> Newly seeded areas are fertilized at the time of seeding with <br /> 18-46-0 ( NPK) pelletized fertilizer at a rate of 400 lbs. per <br /> acre . For certain potassium deficient rock materials, an <br /> additional 200 lbs . per acre of 0-0-60 ( NPK) is applied. If <br /> a revegetated area requires maintenance fertilization , <br /> ammonium nitrate ( 33-0-0 NPK) is applied at a rate of 100-200 <br /> lbs , per acre . <br /> �1 <br /> Fertilizer and seed are applied using a 3, 000 gallon truck- <br /> mounted hydroseeder . Generally , the seed bed is mulched <br /> either with commercial hydromulch at approximately one ton <br /> per acre or blown straw or native hay at approximately four <br /> tons per acre . When hydromulch is used , a commercial tacki- <br /> fier is added to reduce wind loss . Occasionally, very small <br /> or very steep areas are seeded and fertilized by hand using <br /> cyclone seeders . Mesh netting , either jute or plastic, also <br /> may be used in very specific and very steep situations. <br /> -4- <br />
